I bought this hat to finish off my steampunk costume, but it doesn't have anything steampunk on it, so it can work with any costume.The hat is 5.5" wide and 4" tall. There are two coiffure clips under the hat to hold it securely in your hair. It's hard to see in the picture, but the velvet hat has trim/sequins all around its edges and a large bow with a rose on the front. Very cute!
